NOVELTY - Low-odor automobile grease composition comprises 65-92 pts. wt. base oil, 5-20 pts. wt. thickening agent, and 3-15 pts. wt. solid additive. USE - Used as low-odor automobile grease composition. ADVANTAGE - The grease composition: has excellent anti-wear and anti-friction properties, good colloidal stability, shear resistance and excellent high and low temperature performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the low-odor automobile grease composition, comprising (i) using reaction kettle, three-roller grinder and other preparation tool for cleaning; (ii) adding 50% base oil and all stearic acid into the reaction kettle, starting to stir for 5 minutes, orderly adding lithium hydroxide and de-ionized water, sealing the kettle cover, opening the air inlet and exhaust valve, introducing nitrogen into the reaction kettle, nitrogen pressure is 0.12-0.2 Mpa time lasts for 10 plus minus 2 minutes, completely removing the air in the kettle, then closing the air inlet and exhaust valve, starting heating and boosting, the reaction kettle pressure reaches to 0.4 MPa, starting constant temperature and constant pressure timing, constant temperature and constant pressure time is 120 plus minus 5 minutes and pressure 0.4-0.45 Mpa; (iii) after finishing constant temperature and constant pressure, starting to release pressure, continuously heating and stirring in the pressure releasing process, the pressure releasing time is 60 plus minus 10 minutes, the initial stage of pressure releasing should be slowly carried out, then keeping stable, preventing the running material, after the pressure releasing is finished, opening the air inlet and the exhaust valve, continuously introducing nitrogen into the reaction kettle for the second time, nitrogen pressure 0.12-0.2 Mpa time lasts for 10 plus minus 2minutes, completely removing the air and oil steam in the kettle, then closing the air inlet and exhaust valve; (iv) continuously heating and stirring and heating to 210 plus minus 5 degrees C, stopping heating, adding the rest 50% base oil, stirring and cooling to about 130 degrees C, adding solid additive, and then stirring and dispersing for 30 plus minus 5minutes, then discharging into the barrel; and (v) allowing to stand and cooling to room temperature, and grinding the material on the three-roller grinding machine for 3 times.
